Are the OnePlus Nord Buds 4 worth considering? On paper, yes, for most people who want strong noise cancellation, long battery life and gaming-friendly latency in one pair. The Amazon.in listing claims up to 52 dB real-time ANC, six microphones for calls, up to 54 hours of total playback, 10 minutes of charging for up to 11 hours of playback and Bluetooth 6.1, which is an ambitious set of numbers for a Nord-series earbud.
The catch is that several details buyers care about, such as the water-resistance rating, supported codecs and per-earbud battery life, do not appear in the listing we checked. This page covers the Stellar Black variant (model E522A) that the Amazon link below points to.
Please note: this article is based on OnePlus’s published specifications as they appear on the Amazon.in listing (checked on 17 October 2026) and on published launch coverage, not on hands-on testing. OnePlus’s own product page could not be loaded during our research, so each spec is attributed to its source.
The Nord Buds 4 at a glance
- Good fit for: students, commuters and mobile gamers who want high claimed ANC, long battery life and low latency

- Standout claims: 52 dB real-time ANC, six-mic AI call noise reduction, Game Sound spatial audio, 47 ms latency, up to 54 hours of playback, Bluetooth 6.1
- Gaps and limits: no IP rating, codec list or per-bud battery figure on the listing, and the box contents field mentions only ear tips and a user manual

Noise cancellation: what 52 dB means for you
Noise cancellation is the main reason to look at the Nord Buds 4. The Amazon.in listing claims up to 52 dB of real-time ANC across a 5000 Hz frequency range, and FoneArena’s launch report headline also cites up to 52 dB ANC. The technical details list adjustable levels, an automatic mode, real-time adaptive noise control and a transparency mode.
Those modes matter more than the headline number. Adaptive ANC changes its strength based on your surroundings, which helps when you move from a quiet room to a busy street. Transparency mode lets outside sound in, so you can hear a station announcement or talk to someone without removing an earbud. Manual levels are useful if strong ANC causes the pressure sensation some people feel in their ears.
As for the 52 dB figure itself, remember that brands measure peak attenuation under their own conditions, so it cannot be compared directly with another brand’s number. ANC is most effective on constant low-frequency sounds such as engine hum, fans and train rumble, and much less effective against voices and sudden noises. The listing also mentions “adaptive fit-based optimisation”, which suggests the earbuds adjust for how they sit in your ears, but a good ear-tip seal remains essential.
Sound and gaming features
The listing specifies 12 mm dynamic drivers and a “Clear Acoustic Cavity” design that OnePlus describes as pressure-equalising for cleaner, more natural sound and a wider soundstage. Those are design intentions rather than measured results, and we could not open an independent listening review to confirm how the tuning sounds in practice.
Gaming is a clear focus. OnePlus lists Game Sound spatial audio tuned for FPS titles such as BGMI, Free Fire and Call of Duty, aimed at making footsteps, gunshots and directional cues easier to place. Latency is listed at up to 47 ms, which is low for Bluetooth and should help keep sound in step with on-screen action in casual and mid-level play. Serious competitive players may still prefer wired earphones, since any wireless link adds some delay.
The listing does not name the supported Bluetooth codecs. If high-resolution codecs such as LDAC or LHDC matter to you, confirm the codec list on the live listing or OnePlus’s website before ordering.
Calls with six microphones
Each earbud has three microphones, for six in total, and OnePlus says an AI-powered clear-call algorithm keeps your voice in focus even in winds of up to 25 km/h or noisy places. More microphones generally give the software more information to separate your voice from background noise, which helps on calls from roads, markets and canteens.
Even so, call quality is one of the hardest things to judge from a spec sheet. The wind figure is a brand claim, and results depend on how the earbuds fit and how loud your environment is. If you take many work calls outdoors, look for independent call tests before deciding.
Battery and charging
OnePlus claims up to 54 hours of total playback with the case, and FoneArena’s launch report headline gives the same figure. The quick-charge claim is 10 minutes of charging for up to 11 hours of playback with the case, which is handy if you forget to charge overnight.
The listing also mentions TÜV Rheinland Battery Health Certification and says the battery is built to stay strong after 1,000 charging cycles. Battery wear is a real concern for earbuds because their small cells cannot be replaced, so a durability claim like this is welcome, though we could not view the certificate itself.
Two caveats apply. First, the listing does not say whether the 54-hour figure is with ANC on or off. For most earbuds the headline number is measured with ANC off, so expect less with ANC on. Second, it does not give the per-earbud playback, which tells you how long you can listen before returning the buds to the case.
What the listing does not tell you
- Water and dust resistance: no IP rating is stated, so do not assume it is sweat-proof for the gym
- Codecs: not listed
- Per-bud battery and ANC-on battery: not listed
- Dual-device connection: not mentioned in the bullets we checked, so confirm before relying on it
- Box contents: the listing field mentions only ear tips and a user manual, so check whether a USB-C cable is included
- Weight: 42.5 grams is the listing’s item weight, and it is not clear whether this is the earbuds, the earbuds with case, or the package
Is it right for you?
The Nord Buds 4 make sense if you commute by bus or metro, study or work in noisy shared spaces, play mobile shooters, and want a battery that lasts days of mixed use. The combination of adaptive ANC, transparency mode and low latency is well suited to that routine.
Look elsewhere if you need a confirmed IP rating for running or gym sessions, want high-resolution codec support confirmed before you pay, or prefer to wait for independent ANC and call measurements. If you already own the previous model, our OnePlus Nord Buds 3 review can help you judge whether the upgrade is worth it for you.
Other earbuds to compare
These facts are taken from each product’s Amazon.in listing, checked on 17 October 2026.
- realme Buds Air 8 Pro: listed with 55 dB ANC, 11 mm plus 6 mm dual drivers, a six-mic system with a bone-conduction voice sensor, Bluetooth 6.1, 45 ms latency, IP55 and up to 50 hours of playback. A good comparison if you want a stated IP rating
- boAt Nirvana Crown: listed with up to 50 dB hybrid ANC, six mics with AI-ENx, multipoint, in-ear detection, Bluetooth 6.0 and a case with a rotating volume crown, LED ring and haptics, though its Amazon listing does not state total playback
- realme Buds T200: listed with 32 dB ANC, 12.4 mm drivers, 45 ms latency, Hi-Res Audio, dual-mic call noise cancellation, Bluetooth 5.4, up to 50 hours of playback and IP55. Lower claimed ANC, but a stated IP rating
Before you order
A few checks will help you avoid surprises. First, confirm the colour: this link is for the Stellar Black Nord Buds 4 (model E522A), and other colours are separate listings. Second, read the “About this item” section on the live listing for any update on IP rating, codecs or dual connection.
Third, think about after-sales support. The listing states a 1-year manufacturer warranty and names Optiemus Electronics Limited in Noida as the manufacturer, with India as the country of origin. Keep your invoice, and check that the “Sold by” seller on the listing provides a proper GST invoice so warranty claims go smoothly.
Finally, compatibility: the listing names phones, laptops and tablets as compatible devices. As Bluetooth earbuds they can pair with Android phones, iPhones and Windows laptops, but check whether OnePlus’s companion app and features support your phone before relying on them. When you are ready, you can see the Stellar Black OnePlus Nord Buds 4 on Amazon.in.
